Detailed Description

The following describes a portable electronic device according to an embodiment of the present invention. It should be appreciated, however, that the present embodiments provide many suitable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the invention.

Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

These and other aspects, features and advantages of the present invention will become apparent from the following detailed description of a preferred embodiment, which is to be read in connection with the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are referred to only in the direction of the attached drawings. Therefore, the directional terms used in the embodiments are used for description and not for limiting the present invention.

Referring to fig. 1, in which fig. 1 shows a schematic diagram of a portable electronic device according to an embodiment of the invention. As shown in fig. 1, the portable electronic device of the present embodiment is, for example, a notebook computer dedicated for electronic contests (gaming), and mainly includes a main body 10, a display unit 20, and a hinge unit 30; it should be understood that the pivoting unit 30 has a long bar shape, and two ends thereof are respectively pivoted to the main body 10 and the display unit 20, so that the pivoting unit 30 can rotate around the rotation axis H1 relative to the main body 10, and the display unit 20 can rotate around another rotation axis H2 relative to the pivoting unit 30.

As can be seen from fig. 1, when a user wants to use the notebook computer, the user can apply an external force to lift the display unit 20 from the upper surface of the main body 10 (as shown by the arrow in fig. 1), but at this time, the external force may generate a moment on the rotation axis H1 and the rotation axis H2 at the same time, so that when the hinge unit 30 rotates relative to the main body 10, the display unit 20 also rotates relative to the hinge unit 30, which causes difficulty in controlling the angle of the display unit 20 when the notebook computer is opened, thereby causing inconvenience in use.

Referring to fig. 2, fig. 2 is a schematic diagram of a portable electronic device according to another embodiment of the invention. As shown in fig. 2, in order to solve the above problem, in the portable electronic device of the present embodiment, a magnet (not shown) is respectively disposed inside the display unit 20 and the hinge unit 30, so that when the user exerts an external force to lift the display unit 20 from the surface of the main body 10 (as shown by the arrow in fig. 2), the display unit 20 and the hinge unit 30 can be maintained fixed to each other by the attractive force between the magnets and can rotate around the rotation axis H1 together, so as to prevent the display unit 20 from rotating relative to the hinge unit 30 (as shown in fig. 1) during the process of lifting the display unit 20 relative to the main body 10.

After the display unit 20 and the hinge unit 30 are opened to an opening angle relative to the body 10, the user can push the display unit 20 again to turn the display unit 20 to a proper angle (as shown in fig. 3) relative to the hinge unit 30, so as to be beneficial to viewing the screen on the display unit 20; however, since the attractive force between the magnets continuously exists between the display unit 20 and the hinge unit 30, a large force is often applied to flip the display unit 20 relative to the hinge unit 30 when the display unit 20 is flipped, so that the mechanical design of the embodiment still has an improved space.

Next, referring to fig. 4 and 5, fig. 4 is a schematic diagram of a portable electronic device according to another embodiment of the invention, and fig. 5 is a schematic diagram of the display unit 20, the hinge unit 30 located at the left side of the display unit 20, and a driving module 40 located at the right side of the display unit 20 in fig. 4. As shown in fig. 4, the hinge unit 30 of the present embodiment is used to hinge the main body 10 and the display unit 20, wherein a special driving module 40 is disposed inside the housing 301 of the hinge unit 30, so as to solve the problem that the portable electronic device in fig. 2 and 3 is not favorable for the display unit 20 to turn over due to the magnetic attraction between the display unit 20 and the hinge unit 30.

It should be understood that, in the embodiment, the two sides of the display unit 20 are provided with the symmetrical hinge units 30, wherein the housings 301 of the hinge units 30 can be mutually pivoted with the display unit 20 through the pivots, and in addition, the symmetrical driving modules 40 can be arranged inside the housings 301 of the two hinge units 30, however, the driving module 40 can also be arranged inside only one of the hinge units 30, which will be described in advance. In the present embodiment, the driving module 40 on the right side of the display unit 20 is mainly taken as an example for explanation, and the detailed structure thereof is described in detail later.

Referring to fig. 5, 6, 7 and 8, fig. 6 is a schematic diagram illustrating a relative position relationship between the driving module 40 and a pivot S and a first magnet M1 located inside the display unit 20 when the display unit 20 is located at a closing angle relative to the body 10, fig. 7 is a schematic diagram illustrating fig. 6 with the pivot S omitted, and fig. 8 is a schematic diagram illustrating the driving module 40, the pivot S and the display unit 20 in fig. 6 at another viewing angle. In particular, in fig. 6 and 7, the housing on the side of the display unit 20 is not shown, and the first magnet M1 inside the display unit 20 is exposed for convenience of description.

As shown in fig. 6, 7 and 8, the driving module 40 of the present embodiment mainly includes a guiding element 41, a movable element 42, a first gear 43, a sliding block 44, a second gear 45 and a third gear 46 fixed on the housing 301, wherein the first gear 43 and the sliding block 44 are disposed on a first surface 411 of the guiding element 41. As can be seen from fig. 6 and 7, the movable member 42 has a long bar-shaped structure and can slide relative to the guide member 41, wherein a rack portion 421 is formed at the lower end of the movable member 42, the rack portion 421 is movably accommodated in the guide member 41 and is engaged with the first gear 43, and a second magnet M2 is fixedly disposed on the movable member 42 and corresponds to the first magnet M1 inside the display unit 20.

It should be appreciated that when the user lifts the display unit 20 relative to the body 10, the hinge unit 30 and the display unit 20 rotate together about the rotation axis H1 (as shown by the arrow in fig. 4) relative to the body 10 due to the magnetic attraction between the first and second magnets M1, M2. In particular, when the user lifts the display unit 20, the driving module 40 disposed inside the pivot unit 30 rotates relative to the pivot S fixed on the body 10, and at this time, the first gear 43 can be driven by the driving module 40 to rotate, and the rack 421 at the lower end of the movable member 42 drives the second magnet M2 to displace relative to the display unit 20, so as to make it far away from the first magnet M1, thereby reducing or eliminating the magnetic attraction between the first and second magnets M1, M2.

Therefore, when the display unit 20 is opened to the opening angle relative to the body 10, the user can easily turn the display unit 20 over relative to the hinge unit 30, thereby improving the comfort and convenience in use. In this embodiment, the first and second magnets M1, M2 may have a strip structure.

Specifically, the pivot shaft S in this embodiment passes through the guide 41 and is formed with a guide groove portion R (fig. 6) formed with a curved guide groove R1, and a projection 441 (fig. 7) on the slider 44 is located in the guide groove R1. In addition, as shown in fig. 7 and 8, a latch 442 passes through the sliding block 44, the guiding element 41 and the second gear 45 and extends from the first surface 411 of the guiding element 41 to the second surface 412 of the guiding element 41, wherein the latch 442 is located at a first position P1 (fig. 8) relative to the guiding element 41 when the display unit 20 is located at the closing angle relative to the body 10.

As can be seen from fig. 8, the second gear 45 and the third gear 46 are both pivotally arranged on the second surface 412 of the guide member 41, and the second gear 45 and the third gear 46 are engaged with each other; it should be appreciated that the latch 442 passes through the second gear 45, and the first gear 43 and the third gear 46 are coaxially disposed and fixed to each other. Preferably, the second gear 45 and the third gear 46 are not required to be provided, and the latch 442 directly passes through the first gear 43, so that the movable member 42 and the second magnet M2 can be directly driven to displace relative to the guide member 41 and the display unit 20 by the first gear 43.

Referring to fig. 9 and 10, fig. 9 is a schematic diagram illustrating a relative position relationship between the driving module 40 and the pivot S and the first magnet M1 located inside the display unit 20 when the display unit 20 is opened from the closed angle to the open angle relative to the body 10, and fig. 10 is a schematic diagram illustrating the driving module 40, the pivot S and the display unit 20 in fig. 9 from another viewing angle.

As shown in fig. 9 and 10, when the display unit 20 is opened from the closed angle to the open angle relative to the main body 10, the driving module 40 rotates around the pivot S and the guiding groove portion R thereof (as shown by the arrow a1 in fig. 9 and 10), and the protrusion 441 on the slider 44 slides along the curved guiding groove R1 on the guiding groove portion R, so as to guide the slider 44 and the latch 442 to move from the first position P1 to a second position P2 (as shown by the arrow a2 in fig. 10).

During the movement of the slider 44 and the latch 442 from the first position P1 to the second position P2, the second gear 45 and the third gear 46 are sequentially driven and rotate in the directions of arrows A3 and a4 in fig. 10, respectively. As a result, the first gear 43 fixed to the third gear 46 rotates in the direction of the arrow a5 in fig. 9, and the movable member 42 and the second magnet M2 disposed thereon are driven by the rack 421 to move in a first direction (as shown by the arrow a6 in fig. 9). In this way, the second magnet M2 can be far away from the first magnet M1, so as to achieve the purpose of reducing the magnetic attraction between the first and second magnets M1 and M2, wherein the first direction is perpendicular to the pivot S.

On the contrary, when the user finishes using the display unit 20 and rotates the display unit 20 relative to the body 10 from the open angle to the closed angle, the driving module 40 returns to the state shown in fig. 6, 7 and 8, and the second magnet M2 again approaches the first magnet M1 and generates a magnetic attraction force to prevent the display unit 20 and the hinge unit 30 from rotating relative to each other when the display unit 20 is opened from the closed angle relative to the body 10.

In summary, the present invention mainly includes a special driving module disposed inside the pivot unit, wherein when the display unit is opened from a closed angle to an open angle relative to the body, the display unit can be driven by a gear mechanism inside the driving module to separate two magnets respectively disposed inside the display unit and the pivot unit from each other, so as to reduce the magnetic attraction therebetween, thereby solving the problem that the display unit and the pivot unit are not easy to turn due to the magnetic attraction therebetween, and greatly improving the comfort and convenience of the portable electronic device in use.
